Characterization of the MUSE NFM PSF as a function of atmospheric conditions: TipTop calibration
Enrico Congiu, Fuyan Bian, Carlo F. Manara +8
The Multi Unit Spectroscopic Explorer (MUSE) achieves exceptional spatial resolution in narrow-field mode (NFM) thanks to the GALACSI adaptive optics (AO) system. However, limitati…
Data-calibrated point spread function prediction: General description of the method and demonstration on MUSE-NFM
Arseniy Kuznetsov, Benoit Neichel, Sylvain Oberti +1
Precise knowledge of the point spread function (PSF) underpins many data analysis steps in astronomy, from photometry and astrometry to source de-blending and deconvolution. In ada…
Striving towards robust phase diversity on-sky: Implementing LIFT for VLT/MUSE-NFM
Arseniy Kuznetsov, Sylvain Oberti, Benoit Neichel +1
The recent IRLOS upgrade for VLT/MUSE narrow field mode (NFM) introduced a full-pupil mode to enhance sensitivity and sky coverage. This involved replacing the 2x2 Shack-Hartmann s…
TIPTOP: cone effect for single laser adaptive optics systems
Guido Agapito, Cédric Plantet, Fabio Rossi +6
TIPTOP is a python library that is able to quickly compute Point Spread Functions (PSF) of any kind of Adaptive Optics systems. This library has multiple objectives: support the ex…
